Description Randy Tupas 2017-05-09 00:12:26 UTC

In a gnome-wayland session, net-misc/vino-3.22.0 immediately segfaults when attempting to start from the command line (/usr/libexec/vino-server); however, in a gnome-X session, vino can be started successfully from the command-line.

Additionally, the option to enable "Screen Sharing" is missing from gnome-control-center "Sharing" applet when logged in a gnome-wayland session. The option is available in a gnome-X session.

This is the output running "gdb --args /usr/libexec/vino-server", followed by "run":

Actually closing as fixed then (that revision is long stable too)
